How to quickly factory reset an Android phone

Let us assume I am working/living in a potentially hostile environment and want to minimize the risk that somebody can access the data stored on my Android phone. The recommended way is to force-lock the phone to ensure that it cannot be accessed without the password, but this does not fully protect against data extractions applied directly on the phone. And going through the multi-step approach of resetting the phone via Settings is obviously not feasible under pressure. So I am looking for ways to quickly factory reset on an Android phone. Something like "press one icon, confirm with one button = reset Android phone to factory settings".. with no passwords, no PINs... just quick wipe. How can I accomplish this? PS: I am aware that this may also lead to unexpected data loss in case the function is triggered by mistake. That is a risk I am willing to take.
